• Develop and support functionality across order management, inventory, fulfillment, warehouse, and logistics domains.
• Design and implement integrations with upstream and downstream systems such as e-commerce platforms, WMS, ERP, payment systems, and logistics providers.
• Participate in solution design and architecture discussions, evaluating technical approaches and trade-offs.
• Translate complex business requirements into clean, scalable, maintainable, and reusable technical solutions.
• Troubleshoot complex production issues and contribute to root cause analysis, performance optimization, and system reliability.
• Ensure adherence to coding standards, security, performance, scalability, and reliability best practices.
• Collaborate closely with Product Owners, Business Analysts, Architects, QA, DevOps, and other engineering teams.
• Conduct and participate in code reviews and contribute to engineering best practices.
• Mentor junior and mid-level developers and provide technical guidance within the team.
• Participate actively in Agile/Scrum ceremonies, sprint planning, backlog refinement, reviews, and retrospectives.
• Contribute to the continuous improvement of engineering practices, development processes, system architecture, and technical standards.

• Strong hands-on experience with Spring Boot and Spring Framework.
• Strong experience with Hibernate/JPA and ORM concepts.
• Proven experience designing and developing RESTful APIs and microservices.
• Strong understanding of object-oriented design, design patterns, data structures, and software engineering principles.
• Experience working with relational databases such as Oracle, PostgreSQL, MySQL, or similar; exposure to NoSQL databases is a plus.
• Experience with Git or other version control systems.
• Experience working in Agile/Scrum development environments.
• Understanding of CI/CD pipelines, DevOps practices, and automated deployment processes.
